    • Acceleration of cosmic rays in the outer heliosphere 

      Prinsloo, Phillip Lourens (North-West University (South Africa), Potchefstroom Campus, 2016)
      Shortly before the Voyager spacecraft crossed the heliospheric termination shock, they encountered narrow, peak-like enhancements in the intensities of low-energy electrons. These enhancements were associated at the time ...
    • Cosmic ray modulation processes in the heliosphere 

      Vos, Etienne Eben (North-West University, 2011)
      The solar minimum of 2009 has been identified as an exceptional event with regard to cosmic ray (CR)modulation, since conditions in the heliosphere have reached unprecedented quiet levels. This unique minimum has been ...
    • Modelling of galactic cosmic ray electrons in the heliosphere 

      Nndanganeni, Rendani Rejoyce (North-West University, 2012)
      The Voyager 1 spacecraft is now about 25 AU beyond the heliospheric termination shock and soon it should encounter the outer boundary of the heliosphere, the heliopause. This is set to be at 120 AU in the modulation model ...
